摘要： PROBLEM TO BE SOLVED: To provide a plate type heat exchanger which is free from refrigerant leakage. SOLUTION: A plate type heat exchanger is constituted by arranging a plurality of plates 1 for heat exchange in a state where the plates 1 are faced oppositely to each other so that heat exchange may take place between a refrigerant and water (or brine). Each plate 1 is constituted of a metallic plate having a plurality of projections 7 longitudinally extended in parallel on one surface between openings 6 and 6 provided at both end sections in the longitudinal direction and a zigzag heat transfer tube 2 extended in the longitudinal direction and fitted to the other surface. The plates 1 are assembled in such a way that adjacent plates 1 are brought into contact with the heat transfer tube 2 and projections 7, and seal the tube 2 and projections 7 with their peripheral sealing sections 4 in a state where both ends of the tubes 2 are protruded from the sections 4, by using one opening of the first plate as a water inlet and the other opening 6 as a water outlet. Then the refrigerant is supplied to each heat transfer tube 2 and water is supplied from the water inlet 6 of the first plate 1 and made to flow out from the water outlet 6 of the first plate 1 through the space between the plates 1.

摘要： The air conditioning element is constructed as a totally metal sandwich with a light core made of corrugated aluminium and cover layers made of flat aluminium strip. The media guides formed between the corrugated aluminium and cover layers are interconnected by common channels. A pipe union for connection of the media guides to a heating or cooling system is fixed by adhesion to the cover plate through a profiled covering.

摘要： PROBLEM TO BE SOLVED: To reduce weight and to improve heat transfer efficiency, by allowing a metal plate to be thin and bent in a corrugated shape in a peripheral direction, and allowing the amplitude direction of a partial corrugation to be in the thickness direction of an element in a corrugated spacer. SOLUTION: A corrugated spacer 5 is bent in a corrugated shape advancing in the longitudinal direction of a thin metal plate. With the amplitude of the corrugated spacer 5, the top part of the corrugation and the outer surface of a bottom part at a height in contact with the inner surface of each plate in each port end part while a pair of plates 3 and 2 are engaged. With the arrangement state of the corrugated spacer 5, the direction of the amplitude of the corrugation is formed in the thickness direction of all plates, and a heat exchanger is furnished with the corrugated spacer 5 at the port end part of exit/entrance 1 in elements 4 and is also furnished with an inner fin 12. Also, a plurality of stages of elements are laminated and an outer fin 13 is included between them, thus constituting an assembly body. On the other hand, a high- temperature fluid is allowed to flow into each of the elements 4 from the exit/ entrance 1 for cooling by cooling wind and cooling water being circulated at the outer surface side of the elements 4.

摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive grooved planar member by forming the grooved planar member by executing an outer peripheral groove forming stage just before or simultaneously with a zigzag groove forming stage, thereby prohibiting the excess metal of the groove that the outer peripheral groove flows on the front surface side of the planar member and forming the grooves having a uniform cross-sectional shape and a flush opening plane. SOLUTION: A groove part punch member is mounted at the upper base plate of a press and a primarily formed substrate is set at a die member. The press machine is operated and the upper base plate of the press is lowered by prescribed pressure. The outer peripheral groove forming section forms the outer peripheral groove 42 and the zigzag groove forming section forms the zigzag grooves 41 within the base part. The grooved planar member 40 is thus press formed. When the outer peripheral groove 42 is first begun to be formed at this time, the zigzag grooves 41g, 41h are begun to be formed in inclined parts approximately simultaneously. The excess metal flowing to the outer peripheral groove 42 among the excess metals of the zigzag grooves 41g, 41h, therefore, combat against the excess metal flowing to the recessed part side of the outer peripheral groove 42 and the flow of both excess metal does not occur.
